Basically, exposed saddles can be located by using Newton-Raphson search schemes whose initial seeds are real trajectories' initial conditions corresponding to distinct classically allowed pathways (transport) [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}. The Wigner transform is especially useful for this purpose [9]}. For the initial wave packet example defined in the Fig. REF  caption, the Wigner transform is illustrated in
